IPC: H04N1/04
Filed: 1987-03-27
Abstract: PURPOSE:To immediately inform the occurrence of defective reading to the user by providing a means to execute the control operation by a control means before and after reading an original and detecting the result of the control operation. CONSTITUTION:White level is checked just before reading an original and a CPU 7 stores a proper data X1 into a ROM 5. After the end of reading the original, white level check is applied and a proper luminous quantity data X2 obtained by the check similarly as before is stored in the RAM 5 and the processing above is applied by each of LED1-Ln. Then a register for counting the LED is reset again to obtain a difference X between the proper luminous quantity data X1 and X2 obtained by two white level checking to discriminate whether or not the difference is within a permissible range (q1<X<q2). If the difference is at the outside of the permissible range as to one LED, an alarm indication is applied immediately to a display device.

Abstract: PCT No. PCT/CH86/00022 Sec. 371 Date Dec. 1, 1986 Sec. 102(e) Date Dec. 1, 1986 PCT Filed Feb. 18, 1986.Hoistway data which are indicative of predetermined elevator car positions at respective predeterminate hoistway locations, are generated without installations of actuating members in the elevator hoistway and transmitters at the elevator car. For this purpose, a memory is provided and has stored predeterminate positional numbers representative of the predeterminate hoistway locations. The predeterminated positional numbers are transmitted to a register in a travel direction dependent sequence during travel of the associated elevator car. A pulse transmitter is driven by the elevator car and the thus generated pulses are summed-up in a counter to positional numbers which correspond to respective car positions. The positional numbers of the counter and the predeterminate positional numbers transmitted to the register are compared with one another during travel in a comparator during elevator car travel. In case of identity, a signal representing a hoistway datum is generated and a switching member associated with the respective hoistway location is activated.

Abstract: PURPOSE:To control the speed of revolution of a loading motor to be approximately constant even if a load fluctuates and to stabilize a loading and an unloading operations by closed-loop-controlling the speed of revolution of the loading motor, at the time of the loading and the unloading operations. CONSTITUTION:At the time of the loading and the unloading operations, when a control signal MC'1' and the control signal CW/CCW are outputted, a drive voltage VA being supplied to a drive circuit 16 is supplied to a motor 12, and the motor starts to rotate. When the speed of revolution of the motor 12 increases gradually, the output of an F/V converter 21 increases followingly, and a ..ifference voltage between a reference voltage Vref decreases gradually. Consequently, the level of the output signal of a differential amplifier 17 approaches to 0 from a negative direction, and the drive voltage Va decreases gradually from the maximum value. Such the process is repeated, and the speed of revolution of the motor 12 settles at the speed of revolution, determined by the reference voltage Vref. Thus, even if the load fluctuates, the speed of revolution of the motor 12 can be controlled to be approximately constant.
